Description
This article is part of the conference proceedings of the European Coatings Show Conference 2025 held in Nuremberg, Germany, on 25-27 March.
Abstract
PFAS are widely used to provide water and oil repellency for various applications, such as non-sticking utensil pan surfaces, water repellent and anti-soiling treatment for textiles, food-contact anti-soiling coating on paper and/or cardboard packaging or specific paints.
BIO-SUSHY Horizon Europe aims at developing innovative coating solutions that will be designed to meet the policy ambition of the EU’s chemical strategy for sustainability toward a toxic-free environment. BIO-SUSHY particularly targets new biofriendly ways to obtain durable water and oil repellent coatings, without PFAS.
Glass packaging for cosmetic applications has been targeted as one of the BIO-SUSHY case studies. Hybrid organic/inorganic coatings based on sol gel technologies are developed for inner application of cosmetic glass containers to unsure quality, and complete availability of the products and content are protected. With an emphasis on mechanical durability and low adhesion of fluids, BIO-SUSHY coatings aims at minimizing waste through total content recovery and support container reuse strategies. To achieve BIO-SUSHY objectives, the development will be based on 3 pillars: R&I coating development, supported by computational modelling for performances and by SSbD methodology to ensure safety and environmental performances.
This presentation aims at providing an overview of the project concept and methodology. Moreover, the current results obtained with hybrid sol gel coatings applied on glass (for packaging applications) will be presented. Finally, different strategies are explored to meet the targets in terms of wettability properties, durability and safe and sustainable requirements.
